Modifying the System
The MERLIN II communications system is designed so
that you can make changes quickly and easily. If the
system is not at full capacity, you can add an expansion
carrier, additional outside lines or voice terminals, or more
data equipment. Modular plugs on much of the system
wiring and modular components make it easy to
reorganize the MERLIN II system as the customer's needs
change.
With Feature Modules 1 and 2, you cannot switch module
locations nor rearrange the modules on the carriers
without having to readminister the system. Refer to
“Module Installation” on page 2-62 for further
information.
With Release 3, you can replace a module with one of the
same type using On-Line Module Swap. Refer to the
procedure “On-Line Module Swap” on page 4-7 for
additional information.
The most common system changes are adding outside
lines, adding voice terminals, and moving voice terminals.
Contact an equipment supplier to order additional voice
terminals and system modules.
NOTE:
A Frequency Generator must be installed if basic
sets are being used.
ADDING AN OUTSIDE
The MERLIN II system can accommodate up to 56
LINE
outside lines. To add lines to the system, do the following:
1
2
3
Have the local telephone company add the outside
line(s) and network interface.
Refer to “Connecting Outside Lines to the Control
Unit” on page 2-19.
At the control unit, determine if an installed line
module has unused line jacks. If so, simply connect
new lines to the unused line jacks.
